Be it known that I,- RUDOLPH HOFFMAN,

a citizen of the United States, residing at Kankakee, in the county of Kankakee and 6 State of Illinois, have invented certain new and useful Improvements in Gas Burners, of'which the following is a specification.

The invention relates to gas burnerspand .has' for its aim the provision of means for lo'rendering such burners more eliicient and a durable.-

I More specifically, the invention has reference -to gas burnerswhi'ch are'formedof; sheet metal, and one object is tO PIOVIdB- means for preventing. corrosion of the metal around the discharge orifices for the gas.

A further object of the invention is- .to provide in a sheet metal burner elongated discharge apertures or orifices, which in- 80 crease the eflieiency of the'biirnr.

The aim of the; invention, thus generally stated, may be attained by the construction and arrangement illustrated in the accomp'any'ing drawings forming part hereof in 2 which Figural is a top plan view of a-gas burner provided withf'ruseresisting nipples in accordance with my invention. Fig. 21s a, side elevation of the burner. -F1g: 3 .is a sectional view through a portion of the 1 burner, taken on line 3-3 of Fig. 1;-

' The burner comprises gpnerally a base orbody ortion 7 and ane 8. The latter is provi ed with the usual mixing chamber 9. Preferably, the'burner is constructed of sheet metal from two generally similar halves. Thus, it may comprise an .upper 7 section 10 and a lower section 10, the two sections being suitably'joined together as at 11., Any suitable conformation of the parts' forming the body 7 may be employed to' provide intercommunicating annular and j radial channels arra gedhtoeiiect. an even distribution of the m to by the neck 8. v

plurality of 'apertures"12 formed in the upper section 10 and providing dist zharge openingsfor the gas. In order' to provide an elongated orifice and at the same time a flanged outwardly at their upper and lower ends as shown at 14 and 15 (Fig. 3) and Xturie condiietedTfihere: 7

The body portion has'linits upper side a 1525. Serial No. 332,523.

the apertures 12 are defined by an annular inturned flange 16 with the opposite ends of which the flanges 14 and 15 are adapted to engage. Said nipples 1-3 are preferably formed from spun copper or other suitable non-corrosivematerial. The nipples effectively preventthe corrosion of the metal and also provide elongated passageways or orifices which serve to prevent the'flame from passing. into the burner and causing the' ignition and explosion of the gas therein.

It will be understood that by reason. of the sectional construction of the body 7 :the nipples 13-may be conveniently secured in position in the apertures 12, this being accomplished before the two halves of the burner'are assembled.

It will be apparent that my invention has contributed materially to the practicability gases, and by reason of the protection afforded by thenipples, the life of the burner is prolonged almost indefinitely. Moreover,

the construction is such that the nipples may be very readily and eliectively secured in position in the apertures of the burner. ,I claim. as my invention:

1. A gas burner having a plurality of and efficiency of gas burners and especially .for efifecting the-efficient combustion of the openings provided with protective nipples of non-corrosive material extendin wholly through the openings and formmg discharge orifices.

- 2. A gas burner formed of sheet metal and having a plurality of annular flanges defining discharge apertures, each of said apertures being provided with a nipple made of 'nonfcorrosive material and shaped to coact with said annular flange and the apertureso as to be secured in position in the aperture- 3;'A gas burner comprising a main or body portion having upper and lower sections formed from separate sheets of metal secured together, the upper section having a pluraity -of discharge apertures, and 'a plurality ofnipples made of copper or the like entered through said 'apertures and secured upon section...

4. Agas, burner comprising a main or bodyv portion having upper and lower sections formed from separate sheets of metal secured together, the upper Section having a plurality of discharge apertures and a plurality of nipples made of copper or the like mounted in said apertures, said apertures each being defined by an inturned annular flange and each of said nipples having outturned flanges coacting with said in-- opposite sides of .the upper.

turned flange to seeure the nipple in po- SltlOIl. i v

5'. A gas burner formed of sheet metal and having. a plurality of annular flanges defining discharge apertures and a plurality of nipples each providing. an elongated ori- .ficeand shaped to coact with said annular flange and the aperture so as to be secured in position in the aperture. In testimony vwhereof, I have hereunto set my hand.
